So tragic! A young dad shared a sweet photo of his daughter and himself pouting at the camera, but moments later he allegedly shot her in the head as revenge on the girl’s mother! He documented the series of events by posting a series of chilling Facebook statuses.

Merrick McKoy, 22, allegedly shot and killed his 19-month-old daughter, Mia McKoy-Phanthavongsa, at her Colorado home on Nov. 18, moments after posting a selfie with the little girl to his Facebook page. He then turned the gun on himself, but survived his wounds. Police believe his motive was revenge on his estranged ex-girlfriend, the girl’s mother.

Father Posts Facebook Selfie With Daughter Before Murder, Suicide Attempt

Mia’s mother, Kimphone ‘Kim’ Phanthavongsa, 21, “called police to alert them that her ex-boyfriend was inside her apartment with their child and had a handgun,” according to NY Daily News. Kim had a court order of protection against Merrick at the time, following an earlier domestic violence incident, Westminster, Colo. police confirmed to the site.

Merrick updated his Facebook page with a live stream of his motives, posting scary messages as chilling statuses.

“I told u I can’t live without u lol u thought I was joking now me n Mia out this b***h,” Merrick posted. An hour later he followed up, “Don’t judge me had no choice.”

Both father and daughter were rushed to the hospital. Unfortunately, Mia did not survive the bullet wound. Merrick remained in critical condition.

Grieving Mom Reacts To Tragic Shooting

Mia’s mother was “hysterical” about losing her baby, and she wished that her ex had not taken out their relationship issues on their child. “He threatened to kill me, why don’t he just kill me? Why did he have to go kill my daughter?” Kim told FOX31 Denver. After Kim called the police to report her ex’s threats, she could not believe what happened. “I was on the phone with the officer … next thing I heard is a gunshot. That’s my thought — that he shot my daughter,” she told the news.

Investigator Cheri Spottke called the incident “particularly heinous,” according to NY Daily News.
